Previous research discusses students' difficulties in grasping an operational understanding of covariational reasoning. In this study, I interviewed four undergraduate students in calculus and pre-calculus classes to determine their ways of thinking when working on an animated covariation problem. With previous studies in mind and with the use of technology, I devised an interview method, which I structured using multiple phases of pre-planned support. With these interviews, I gathered information about two main aspects about students' thinking: how students think when attempting to reason covariationally and which of the identified ways of thinking are most propitious for the development of an understanding of covariational reasoning. I will discuss how, based on interview data, one of the five identified ways of thinking about covariational reasoning is highly propitious, while the other four are somewhat less propitious.

Description
The purpose of this study was to investigate: 1) within police departments in Maricopa County, exactly who helps the families left behind after a domestic homicide occurs? 2) What kind of short-term resources are offered by the police to immediately help the family and any children affected? And 3) are long-term services provided to the family and children of domestic homicide victims, and if not, to where is the family referred? To answer these questions, employees from each of the 14 city police departments in Maricopa County were interviewed. Participants answered a serious of both open-ended and scale questions either via email or over the phone. This study found that all police departments in cities of Maricopa County (with the exception of Litchfield Park, which is covered by the Sherriff's Office) have what is referred to as a Victim Services Unit. This is a small team comprised of social workers and other employees specifically trained to provide a continuation of support to victims from the crisis period through the investigative and judicial processes. In terms of services provided, this study found that most of the services offered to victims through police departments in Maricopa County are short-term in nature and fall under one of the following categories: On-scene crisis intervention and initial needs-assessments, immediate basic needs and referrals, financial resources, counseling, family advocacy centers, legal advocacy and assistance with the criminal process, or Child Protective Services. Results also indicated a positive relationship between city size and the amount of resources provided to victims after a homicide. Finally, in regards to long-term resources, this study found in general, all long-term needs are handled by social service agencies and non-profits, which victims are connected to by police departments after a needs assessment has been conducted. Based on these findings, a number of recommendations were made to Purple Ribbon Council, a domestic abuse prevention and supportive care non-profit that were designed to help Purple Ribbon Council increase its reach and effectiveness.

Description
Although discrimination is implicated in ethnic health disparities, social support may buffer against its negative effects on health. This study investigated whether prenatal maternal discrimination and social support would predict postpartum cortisol in low-income Hispanic women and infants. Among infants whose mothers reported high discrimination, low maternal social support was associated with high infant cortisol (ß= -0.293, p= 0.03). This provides evidence for the social buffering hypothesis.

Description
As the student union on Arizona State University’s main Tempe campus, the MU should be a model of building sustainability. After a fire engulfed the MU’s second floor in 2007, the building underwent major renovations and achieved LEED v2.0: Commercial Interiors (LEED CI) Gold certification. Since then, more up-to-date building certification programs have been established, including the Green Globes (GG) green building rating system and a more recent version of LEED that suits the MU’s situation—Existing Buildings: Operations and Maintenance (LEED EB:OM). This paper performs a cost-benefit analysis of these rating systems, specifically looking at 1) national recognition, 2) ease of use, 3) amount of resources needed to invest, 4) length of time of the certification process, 5) certification fees and costs, 6) pre-requisites and system structure of point allotment, and 7) flexibility of the systems. A review of the previous LEED CI certification of the MU addresses 1) solar panel installation and renewable energy achievements, 2) improvement of indoor air quality, 3) application of sustainable construction practices, 4) missed opportunities since renovations were not performed on the entire building, 5) water efficiency scoring, and 6) lack of significant Energy & Atmosphere improvements. A proposal for the university to consider LEED EB:OM certification for the Memorial Union will be presented, analyzing the points already secured by campus-wide programs and policies, credits that are possible with minimal funding, and elaborating on opportunities already planned for completion, including 1) the Power Parasol project, 2) “Zero Waste by 2015” and “Carbon Neutrality” programs and goals, and 3) plans for alternative transportation methods through the Tempe Campus Access Management Plan. In conclusion, my recommendation to pursue LEED EB:OM and achieve Silver level will be presented. With the majority of LEED points already secured and several on the horizon, certifying the MU under LEED EB:OM will set an example and increase the amount of existing buildings on campus to pursue LEED certification. University-wide policies on green cleaning, sustainable purchasing, alternative energy sources, carbon neutrality, and LEED for Multiple Buildings all contribute to simplifying the LEED certification process for ASU buildings campus-wide.

Description
The Community Action Research Experiences program integrates the research and teaching mission of Arizona State University by providing services to the community by fostering professional and leadership development of students. It is hoped that the results of the collaborations with CARE will serve to further an organization's goals and effectiveness. VALLEYLIFE (VL) is a non-profit organization striving to help people with disabilities. VL develops Action Programs for each of its clients, whom they call members, to improve their independent or social skills. Examples of programs that members may work on include tasks such as computer training, visual arts, or writing. VALLEYLIFE lacked the data to evaluate if the developed and implemented Action Programs are properly carried out by the staff in ways that are beneficial to members. Given the problem, this research project sought to conduct a process evaluation of the staff regarding their implementation of the Action Programs. This involved observations of employee-member interactions in performing the Action Programs and an interview of staff measuring their preparedness and confidence in performing the program and their feelings of the programs and how things are run. This research provided the following implications to VALLEYLIFE. VL might consider performing periodic observations and reviews of the program implementation to monitor quality. VL may consider involving staff in program development and revision to create programs that better serve members. VL may consider generating ideas for how they may cooperate when a peer is struggling to keep up with events that happen through the day in the interest of better serving the members. Overall, employees are doing well as they are efficient in carrying out the written programs during program time. They are comfortable with what they are doing, use time effectively, and do their best to help the members. There is always room for improvement however and by considering some of the implications mentioned, VALLEYLIFE and their employees may be able to take action that may hold potential for further improvements in effectiveness.

Description
Children's speech and language development is measured by performance on standardized articulation tests. Test items on these assessments, however, vary in length and complexity. Word complexity was compared across five articulation tests: the Assessment of Phonological Patterns-Revised (APP-R), the Bankson-Bernthal Test of Phonology (BBTOP), the Clinical Assessment of Articulation and Phonology (CAAP), the Goldman-Fristoe Test of Articulation (GFTA), and the Assessment of Children's Articulation and Phonology (ACAP). Four groups of word complexity were used, using the dimensions of monosyllabic vs. multisyllabic words, and words with consonant clusters vs. words without consonant clusters. The measure of phonological mean length of utterance (Ingram, 2001), was used to assess overall word complexity. It was found that the tests varied in number of test items and word complexity, with the BBTOP and the CAAP showing the most similarity to word complexity in spontaneous speech of young children. On the other hand, the APP-R used the most complex words and showed the least similarity. Additionally, case studies were analyzed for three of the tests to examine the effect of word complexity on consonant correctness, usedin the measures of Percentage of Correct Consonants (PCC) and the Proportion of Whole Word Proximity (PWP). Word complexity was found to affect consonant correctness, therefore affecting test performance.

Description
This project began when I heard a story that made my mind turn. The story was about a five- year-old girl who left her glove in the car on a chilly morning before school. Upon reaching the school entrance, she turned to her mother and cried, "Oh no! Mom! I'm Doomed!!" because she neglected to put on one of her gloves (Snow, 2012). Her mother, astonished by her daughter's mature answer, asked her daughter where she had heard that word before. The daughter explained that The Marley brothers told Scrooge this in the production of "A Christmas Carol" that she was participating in at the time. After hearing this story, I began to ponder the impact scripts and theatrical participation could have on a child's literacy skills, especially a child's vocabulary. Being involved in theatre since a very young age, I decided it was time to put her theory into a research project. "Mom, I'm DOOMED!" Literacy Development Through Theatrical Participation sets out to answer three main research questions: (1) How does theatrical participation benefit students' literacy skills? (2) How do scripts enhance students' vocabulary? (3) How do scripts and theatrical participation heighten students' fluency skills? In order to explore these research questions, the researcher created a theatrical workshop to engage students in an authentic theatrical experience. Using a fourth grade reader's theatre script and on-grade-level vocabulary words, I created a six-day workshop to engage students and gather data surrounding her research questions. After the workshop was conducted and data gathered, the results were analyzed for common trends and correlations. Although the results found were minimal, they did show a positive correlation between theatrical participation and students' literacy skills. Although students' data did show improvement in scores, there were no clear findings that could prove theatrical participation is a more effective learning environment than others.

Description
Our goal was to design a method to express soluble folded major histocompatibility complex (MHC) proteins using human cell line HeLa lysate with the novel 1-Step Human In Vitro Protein Expression by Thermo Scientific in the presence of β2 microglobulin (β2m) and antigenic peptide.
We confirmed that the soluble protein MHC-A2.1 could be successfully attached to the Luminex magnetic beads and detected using the primary antibody anti-GST and the detection antibody goat mAb mouse PE. The average net MFI of the attached pA2.1-bead complex was 8182. Biotinylated A2.1 MHC complexes pre-folded with β2m and FLU M1 peptide (A2.1 monomers) were also successfully attached to Luminex magnetic beads and detected with BB7.2. The average net MFI of the detected A2.1 monmer-bead complexes was 318. The protein MHC complexes were multimerized on magnetic beads to create MHC tetramers and detected with BB7.2, PE labeled monoclonal antibody, via median fluorescent intensity with the Luminex platform. Varying protein, β2 microglobulin (β2m), and peptide concentrations were tested in a number of MHC-A2.1 protein refolding trials. Different antigenic peptides and attachment methods were also tested. However, none of the MHC-A2.1 protein folding and capture trials were successful. Although MHC-A2.1 complexes and recombinant MHC molecules could be attached to Luminex magnetic beads and be detected by Luminex arrays, soluble protein A2.1 could not be successfully expressed, refolded, captured onto Luminex beads, and detected. All refolding trials resulted in a net MFI of <25. The failed refolding and capture trials of A2.1 lead to the conclusion that human cell line HeLa lysate cannot be used to properly fold MHC molecules. However, efforts to refold the complexes onto Luminex magnetic beads are ongoing. We are also using the baculovirus expression system to refold soluble A2.1 lysate onto peptide-bead complexes.

Description
This was a social movements analysis of the protests against Arizona's Senate Bill 1070, better known as the "Show Me your Papers" law. The project looked at the role religious organizations and religious leaders took in the protests as part of the immigration rights movement in Arizona. It was found that there were frames, networks, and resources already in place when SB 1070 passed in 2010. Rather than a movement emerging as a response to the legislation, it looked more like a social movement in crisis. The established frames, networks, and resources allowed this social movement to meet the challenge and have some measure of success in resisting and overturning SB 1070.
